DETAILED DESCRIPTION

Field crops are bred through techniques that take advantage of theplant's method of pollination. A plant is self-pollinated if pollen fromone flower is transferred to the same or another flower of the sameplant or a genetically identical plant. A plant is sib-pollinated whenindividuals within the same family or line are used for pollination. Aplant is cross-pollinated if the pollen comes from a flower on agenetically different plant from a different family or line. The term“cross-pollination” used herein does not include self-pollination orsib-pollination.

The breeder often initially selects and crosses two or more parentallines, followed by repeated selfing and selection, thereby producingmany unique genetic combinations. In each cycle of evaluation, the plantbreeder selects the germplasm to advance to the next generation. Thisgermplasm is grown under chosen geographical, climatic, and soilconditions, and further selections are then made. The unpredictabilityof genetic combinations commonly results in the expenditure of largeeffort to develop a new and superior canola variety.

Canola breeding programs utilize techniques such as mass and recurrentselection, backcrossing, pedigree breeding and haploidy.

Recurrent selection is used to improve populations of either self- orcross-pollinating Brassica. Through recurrent selection, a geneticallyvariable population of heterozygous individuals is created byintercrossing several different parents. The best plants are selectedbased on individual superiority, outstanding progeny, and/or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued. Variousrecurrent selection techniques are used to improve quantitativelyinherited traits controlled by numerous genes.

Breeding programs use backcross breeding to transfer genes for a simplyinherited, highly heritable trait into another line that serves as therecurrent parent. The source of the trait to be transferred is calledthe donor parent. After the initial cross, individual plants possessingthe desired trait of the donor parent are selected and are crossed(backcrossed) to the recurrent parent for several generations. Theresulting plant is expected to have the attributes of the recurrentparent and the desirable trait transferred from the donor parent. Thisapproach has been used for breeding disease resistant phenotypes of manyplant species, and has been used to transfer low erucic acid and lowglucosinolate content into lines and breeding populations of Brassica.

Pedigree breeding and recurrent selection breeding methods are used todevelop varieties from breeding populations. Pedigree breeding startswith the crossing of two genotypes, each of which may have one or moredesirable characteristics that is lacking in the other or whichcomplements the other. If the two original parents do not provide all ofthe desired characteristics, other sources can be included in thebreeding population. In the pedigree method, superior plants are selfedand selected in successive generations. In the succeeding generationsthe heterozygous condition gives way to homogeneous lines as a result ofself-pollination and selection. Typically, in the pedigree method ofbreeding, five or more generations of selfing and selection arepracticed: F₁ to F₂; F₂ to F₃; F₃ to F₄; F₄ to F₅, etc. For example, twoparents that are believed to possess favorable complementary traits arecrossed to produce an F₁. An F₂ population is produced by selfing one orseveral F₁'s or by intercrossing two F₁'s (i.e., sib mating). Selectionof the best individuals may begin in the F₂ population, and beginning inthe F₃ the best individuals in the best families are selected.Replicated testing of families can begin in the F₄ generation to improvethe effectiveness of selection for traits with low heritability. At anadvanced stage of inbreeding (i.e., F₆ and F₇), the best lines ormixtures of phenotypically similar lines commonly are tested forpotential release as new cultivars. Backcrossing may be used inconjunction with pedigree breeding; for example, a combination ofbackcrossing and pedigree breeding with recurrent selection has beenused to incorporate blackleg resistance into certain cultivars ofBrassica napus.

Plants that have been self-pollinated and selected for type for manygenerations become homozygous at almost all gene loci and produce auniform population of true breeding progeny. If desired, double-haploidmethods can also be used to extract homogeneous lines from inbredCL233163. A cross between two different homozygous lines produces auniform population of hybrid plants that may be heterozygous for manygene loci. A cross of two plants each heterozygous at a number of geneloci will produce a population of hybrid plants that differ geneticallyand will not be uniform.

The choice of breeding or selection methods depends on the mode of plantreproduction, the heritability of the trait(s) being improved, and thetype of cultivar used commercially, such as F₁ hybrid variety or openpollinated variety. A true breeding homozygous line can also be used asa parental line (inbred line) in a commercial hybrid. If the line isbeing developed as an inbred for use in a hybrid, an appropriatepollination control system should be incorporated in the line.Suitability of an inbred line in a hybrid combination will depend uponthe combining ability (general combining ability or specific combiningability) of the inbred.

Various breeding procedures can be utilized with these breeding andselection methods and inbred CL233163. The single-seed descent procedurein the strict sense refers to planting a segregating population,harvesting a sample of one seed per plant, and using the one-seed sampleto plant the next generation. When the population has been advanced fromthe F₂ to the desired level of inbreeding, the plants from which linesare derived will each trace to different F₂ individuals. The number ofplants in a population declines each generation due to failure of someseeds to germinate or some plants to produce at least one seed. As aresult, not all of the F₂ plants originally sampled in the populationwill be represented by a progeny when generation advance is completed.

In a multiple-seed procedure, one or more pods from each plant in apopulation are threshed together to form a bulk. Part of the bulk isused to plant the next generation and part is put in reserve. Theprocedure has been referred to as modified single-seed descent or thepod-bulk technique. It is considerably faster to thresh pods with amachine than to remove one seed from each by hand for the single-seedprocedure. The multiple-seed procedure also makes it possible to plantthe same number of seeds of a population each generation of inbreeding.Enough seeds are harvested to make up for those plants that did notgerminate or produce seed. If desired, doubled-haploid methods can beused to extract homogeneous lines.

Molecular markers, including techniques such as Isozyme Electrophoresis,Restriction Fragment Length Polymorphisms (RFLP), random amplifiedpolymorphic DNA (RAPD), amplified fragment length polymorphism (AFLP),inter-simple sequence repeats (ISSRs), sequence characterized regions(SCARs), sequence tag sites (STSs), cleaved amplified polymorphicsequences (CAPS), microsatellites, simple sequence repeats (SSRs),expressed sequence tags (ESTs), single nucleotide polymorphisms (SNPs),and diversity arrays technology (DArT), sequencing, and the like may beused in plant breeding methods using CL233163. One use of molecularmarkers is Quantitative Trait Loci (QTL) mapping. QTL mapping is the useof markers which are known to be closely linked to alleles that havemeasurable effects on a quantitative trait. Selection in the breedingprocess is based upon the accumulation of markers linked to the positiveeffecting alleles and/or the elimination of the markers linked to thenegative effecting alleles in the plant's genome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against themarkers of the donor parent. Using this procedure can minimize theamount of genome from the donor parent that remains in the selectedplants. It can also be used to reduce the number of crosses back to therecurrent parent needed in a backcrossing program. The use of molecularmarkers in the selection process is often called Genetic Marker EnhancedSelection or Marker Assisted Selection (MAS).

Methods of isolating nucleic acids from CL233163 and methods forperforming genetic marker profiles using SNP and SSR polymorphisms areprovided. SNPs are genetic markers based on a polymorphism in a singlenucleotide. A marker system based on SNPs can be highly informative inlinkage analysis relative to other marker systems in that multiplealleles may be present.

A method comprising isolating nucleic acids, such as DNA, from a plant,a plant part, plant cell or a seed of the canola varieties disclosedherein is provided. The method can include mechanical, electrical and/orchemical disruption of the plant, plant part, plant cell or seed,contacting the disrupted plant, plant part, plant cell or seed with abuffer or solvent, to produce a solution or suspension comprisingnucleic acids, optionally contacting the nucleic acids with aprecipitating agent to precipitate the nucleic acids, optionallyextracting the nucleic acids, and optionally separating the nucleicacids such as by centrifugation or by binding to beads or a column, withsubsequent elution, or a combination thereof. If DNA is being isolated,an RNase can be included in one or more of the method steps. The nucleicacids isolated can comprise all or substantially all of the genomic DNAsequence, all or substantially all of the chromosomal DNA sequence orall or substantially all of the coding sequences (cDNA) of the plant,plant part, or plant cell from which they were isolated. The nucleicacids isolated can comprise all, substantially all, or essentially allof the genetic complement of the plant. The nucleic acids isolated cancomprise a genetic complement of the canola variety. The amount and typeof nucleic acids isolated may be sufficient to permit whole genomesequencing of the plant from which they were isolated or chromosomalmarker analysis of the plant from which they were isolated.

The methods can be used to produce nucleic acids from the plant, plantpart, seed or cell, which nucleic acids can be, for example, analyzed toproduce data. The data can be recorded. The nucleic acids from thedisrupted cell, the disrupted plant, plant part, plant cell or seed orthe nucleic acids following isolation or separation can be contactedwith primers and nucleotide bases, and/or a polymerase to facilitate PCRsequencing or marker analysis of the nucleic acids. In some examples,the nucleic acids produced can be sequenced or contacted with markers toproduce a genetic profile, a molecular profile, a marker profile, ahaplotype, or any combination thereof. In some examples, the geneticprofile or nucleotide sequence is recorded on a computer readablemedium. In other examples, the methods may further comprise using thenucleic acids produced from plants, plant parts, plant cells or seeds ina plant breeding program, for example in making crosses, selectionand/or advancement decisions in a breeding program. Crossing includesany type of plant breeding crossing method, including but not limited tocrosses to produce hybrids, outcrossing, selfing, backcrossing, locusconversion, introgression and the like. Favorable genotypes and ormarker profiles, optionally associated with a trait of interest, may beidentified by one or more methodologies. In some examples one or moremarkers are used, including but not limited to restriction fragmentlength polymorphism (RFLP), random amplified polymorphic DNA (RAPD),amplified fragment length polymorphism (AFLP), inter-simple sequencerepeats (ISSRs), sequence characterized regions (SCARs), sequence tagsites (STSs), cleaved amplified polymorphic sequences (CAPS),microsatellites, simple sequence repeats (SSRs), expressed sequence tags(ESTs), single nucleotide polymorphisms (SNPs), and diversity arraystechnology (DArT), sequencing, and the like. In some methods, a targetnucleic acid is amplified prior to hybridization with a probe. In othercases, the target nucleic acid is not amplified prior to hybridization,such as methods using molecular inversion probes. In some examples, thegenotype related to a specific trait is monitored, while in otherexamples, a genome-wide evaluation including but not limited to one ormore of marker panels, library screens, association studies,microarrays, gene chips, expression studies, or sequencing such aswhole-genome resequencing and genotyping-by-sequencing (GBS) may beused. In some examples, no target-specific probe is needed, for exampleby using sequencing technologies, including but not limited tonext-generation sequencing methods (see, for example, Metzker (2010) NatRev Genet 11:31-46; and, Egan et al. (2012) Am J Bot 99:175-185) such assequencing by synthesis (e.g., Roche 454 pyrosequencing, Illumina GenomeAnalyzer, and Ion Torrent PGM or Proton systems), sequencing by ligation(e.g., SOLiD from Applied Biosystems, and Polnator system from AzcoBiotech), and single molecule sequencing (SMS or third-generationsequencing) which eliminate template amplification (e.g., Helicossystem, and PacBio RS system from Pacific BioSciences). Furthertechnologies include optical sequencing systems (e.g., Starlight fromLife Technologies), and nanopore sequencing (e.g., GridION from OxfordNanopore Technologies). Each of these may be coupled with one or moreenrichment strategies for organellar or nuclear genomes in order toreduce the complexity of the genome under investigation via PCR,hybridization, restriction enzyme (see, e.g., Elshire et al. (2011) PLoSONE 6:e19379), and expression methods. In some examples, no referencegenome sequence is needed in order to complete the analysis. CL233163and its plant parts can be identified through a molecular markerprofile. Such plant parts may be either diploid or haploid. Alsoencompassed and described are plants and plant parts substantiallybenefiting from the use of variety CL233163 in their development, suchas variety CL233163 comprising a locus conversion or single locusconversion.

The production of doubled haploids can also be used for the developmentof inbreds from CL233163 in a breeding program. In Brassica napus,microspore culture technique is used in producing haploid embryos. Thehaploid embryos are then regenerated on appropriate media as haploidplantlets, doubling chromosomes of which results in doubled haploidplants. This can be advantageous because the process omits thegenerations of selfing needed to obtain a homozygous plant from aheterozygous source.

Controlling Self-Pollination

Canola varieties are mainly self-pollinated. A pollination controlsystem and effective transfer of pollen from one parent to the otherprovides an effective method for producing hybrid canola seed andplants. For example, the ogura cytoplasmic male sterility (CMS) system,developed via protoplast fusion between radish (Raphanus sativus) andrapeseed (Brassica napus), is one of the most frequently used methods ofhybrid production. It provides stable expression of the male sterilitytrait and an effective nuclear restorer gene. The OGU INRA restorergene, Rf1 originating from radish has improved versions.

Brassica hybrid varieties can be developed using self-incompatible (SI),cytoplasmic male sterile (CMS) or nuclear male sterile (NMS) Brassicaplants as the female parent such that only cross pollination will occurbetween the hybrid parents.

In one instance, production of F₁ hybrids includes crossing a CMSBrassica female parent with a pollen-producing male Brassica has afertility restorer gene (Rf gene). The presence of an Rf gene means thatthe F₁ generation will not be completely or partially sterile, so thateither self-pollination or cross pollination may occur. Self pollinationof the F₁ generation to produce several subsequent generations verifiesthat a desired trait is heritable and stable and that a new variety hasbeen isolated.

Other sources and refinements of CMS sterility in canola include thePolima cytoplasmic male sterile plant, as well as those of U.S. Pat. No.5,789,566, DNA sequence imparting cytoplasmic male sterility,mitochondrial genome, nuclear genome, mitochondria and plant containingsaid sequence and process for the preparation of hybrids; See U.S. Pat.Nos. 4,658,085, 5,973,233 and 6,229,072.

Hybrid Development

For many traits the true genotypic value may be masked by otherconfounding plant traits or environmental factors. One method foridentifying a superior plant is to observe its performance relative toother experimental plants and to one or more widely grown standardvarieties. If a single observation is inconclusive, replicatedobservations provide a better estimate of the genetic worth.

As a result of the advances in sterility systems, lines are developedthat can be used as an open pollinated variety (i.e., a purelinecultivar) and/or as a sterile inbred (female) used in the production ofF₁ hybrid seed. In the latter case, favorable combining ability with arestorer (male) would be desirable.

The development of a canola hybrid generally involves three steps: (1)the selection of plants from various germplasm pools for initialbreeding crosses; (2) generation of inbred lines, such as by selfing ofselected plants from the breeding crosses for several generations toproduce a series of different inbred lines, which breed true and arehighly uniform; and (3) crossing the selected inbred lines withdifferent inbred lines to produce the hybrids.

Combining ability of a line, as well as the performance of the line perse, is a factor in the selection of improved canola lines that may beused as inbreds. Combining ability refers to a line's contribution as aparent when crossed with other lines to form hybrids. The hybrids formedfor the purpose of selecting superior lines are designated test crosses.One way of measuring combining ability is by using breeding values.Breeding values are based on the overall mean of a number of testcrosses. This mean is then adjusted to remove environmental effects andit is adjusted for known genetic relationships among the lines.

Brassica napus canola plants, absent the use of sterility systems, arerecognized to commonly be self-fertile with approximately 70 to 90percent of the seed normally forming as the result of self-pollination.The percentage of cross pollination may be further enhanced whenpopulations of recognized insect pollinators at a given growing site aregreater. Thus open pollination is often used in commercial canolaproduction.

Locus Conversions of Canola Variety CL233163

CL233163 represents a new base genetic line into which a new locus ortrait may be introduced. Direct transformation, genetic editing or genemodification such as described herein and backcrossing can be used toaccomplish such an introgression. The term locus conversion is used todesignate the product of such an introgression.

Backcrossing can be used to improve inbred varieties and a hybridvariety which is made using those inbreds. Backcrossing can be used totransfer a specific desirable trait from one variety, the donor parent,to an inbred called the recurrent parent which has overall goodagronomic characteristics yet that lacks the desirable trait. Thistransfer of the desirable trait into an inbred with overall goodagronomic characteristics can be accomplished by first crossing arecurrent parent to a donor parent (non-recurrent parent). The progenyof this cross is then mated back to the recurrent parent followed byselection in the resultant progeny for the desired trait to betransferred from the non-recurrent parent.

Traits may be used by those of ordinary skill in the art to characterizeprogeny. Traits are commonly evaluated at a significance level, such asa 1%, 5% or 10% significance level, when measured in plants grown in thesame environmental conditions. For example, a locus conversion ofCL233163 may be characterized as having essentially the same phenotypictraits as CL233163 or otherwise all of the physiological andmorphological characteristics of CL233163. The traits used forcomparison may be those traits shown in Table 1. Molecular markers canalso be used during the breeding process for the selection ofqualitative traits. For example, markers can be used to select plantsthat contain the alleles of interest during a backcrossing breedingprogram. The markers can also be used to select for the genome of therecurrent parent and against the genome of the donor parent. Using thisprocedure can minimize the amount of genome from the donor parent thatremains in the selected plants.

A locus conversion of CL233163 may contain at least 1, 2, 3, 4 or 5locus conversions, and fewer than 15, 10, 9, 8, 7, or 6 locusconversions. A locus conversion of CL233163 will otherwise retain thegenetic integrity of CL233163. For example, a locus conversion ofCL233163 can be developed when DNA sequences are introduced throughbackcrossing, with a parent of CL233163 utilized as the recurrentparent. Both naturally occurring and transgenic DNA sequences may beintroduced through backcrossing techniques. A backcross conversion mayproduce a plant with a locus conversion in at least one or morebackcrosses, including at least 2 crosses, at least 3 crosses, at least4 crosses, at least 5 crosses and the like. Molecular marker assistedbreeding or selection may be utilized to reduce the number ofbackcrosses necessary to achieve the backcross conversion. For example,a backcross conversion can be made in as few as two backcrosses. A locusconversion of CL233163 can be determined through the use of a molecularprofile. A locus conversion of CL233163 may have at least 92%, 93%, 94%,95%, 96%, 97%, 98% or 99% of the molecular markers, or molecularprofile, of CL233163. Examples of molecular markers that could be usedto determine the molecular profile include RFLP, PCR analysis, SSR andSNPs.

Examples of locus conversions or transgenes which may be using includeone or more that confer male sterility, a site for site-specificrecombination, abiotic stress tolerance, altered phosphate content,altered antioxidants, altered fatty acid content, altered essentialamino acid content, altered carbohydrate content, herbicide resistance,insect resistance, disease resistance or a combination thereof. Otherdesirable traits which may be modified include tolerance to heat anddrought, reducing the time to crop maturity, greater yield, and betteragronomic quality, increased amount or rate of germination, standestablishment, growth rate, maturity, and plant and pod height.

Disease—Sclerotinia

Sclerotinia infects over 100 species of plants, including Brassicaspecies. Sclerotinia sclerotiorum is responsible for over 99% ofSclerotinia disease, while Sclerotinia minor produces less than 1% ofthe disease. Sclerotinia produces sclerotia, irregularly-shaped, darkoverwintering bodies, which can endure in soil for four to five years.The sclerotia can germinate carpogenically or myceliogenically,depending on the environmental conditions and crop canopies. The twotypes of germination cause two distinct types of diseases. Sclerotiathat germinate carpogenically produce apothecia and ascospores thatinfect above-ground tissues, resulting in stem blight, stalk rot, headrot, pod rot, white mold and blossom blight of plants. Sclerotia thatgerminate myceliogenically produce mycelia that infect root tissues,causing crown rot, root rot and basal stalk rot.

Sclerotinia causes Sclerotinia stem rot, also known as white mold, inBrassica, including canola. The disease is favored by moist soilconditions (at least 10 days at or near field capacity) and temperaturesof 15-25° C., prior to and during canola flowering. The spores cannotinfect leaves and stems directly; they must first land on flowers,fallen petals, and pollen on the stems and leaves. The fungal spores usethe flower parts as a food source as they germinate and infect theplant.

The severity of Sclerotinia in Brassica is variable, and is dependent onthe time of infection and climatic conditions, being favored by cooltemperatures between 20 and 25° C., prolonged precipitation and relativehumidities of greater than 80%. Losses ranging from 5 to 100% have beenreported for individual fields. Sclerotinia can cause heavy losses inwet swaths and result in economic losses of millions of dollars.

The symptoms of Sclerotinia infection usually develop several weeksafter flowering begins. The infections often develop where the leaf andthe stem join. Infected stems appear bleached and tend to shred. Hardblack fungal sclerotia develop within the infected stems, branches, orpods. Plants infected at flowering produce little or no seed. Plantswith girdled stems wilt and ripen prematurely. Severely infected cropsfrequently lodge, shatter at swathing, and make swathing more timeconsuming. Infections can occur in all above-ground plant parts,especially in dense or lodged stands, where plant-to-plant contactfacilitates the spread of infection. New sclerotia carry the diseaseover to the next season.

Conventional methods for control of Sclerotinia diseases include (a)chemical control (fungicides such as benomyl, vinclozolin, iprodione,azoxystrobin, prothioconazole, boscalid), (b) disease resistance (suchas partial resistance and breeding for favorable morphologies such asincreased standability, reduced petal retention, branching (less compactand/or higher), and early leaf abscission) and (c) cultural control.

Methods for generating Sclerotinia resistant Brassica plants usinginbred line CL233163 are provided, including crossing with one or morelines containing one or more genes contributing to Sclerotiniaresistance and selecting for resistance. In some embodiments, CL233163can be modified to have resistance to Sclerotinia.

The inbred line CL233163 can be used in breeding techniques to createcanola hybrids. For example, inbred line CL233163 may be used as afemale parent, male parent or restorer (R-line), A-line, maintainer(B-line) in a canola hybrid.

An OGU restorer version, or R-line, of variety CL233163 is providedwhich is a male line that carries a gene for the restoration offertility. When a sterile CMS version of an inbred is pollinated by amale line that carries a gene for the restoration of fertility, itresults in a fertile hybrid. Generally, the seed produced from thiscross is the seed that is commercially sold.

There are a number of analytical methods available to determine thephenotypic stability of a canola variety. Phenotypic trait data areusually collected in field experiments including for example traitsassociated with seed yield, seed oil content, seed protein content,fatty acid composition of oil, glucosinolate content of meal, growthhabit, lodging resistance, plant height, shattering resistance, etc.

In addition to phenotypic observations, the genotype of a plant can alsobe examined. A plant's genotype can be used to identify plants of thesame variety or a related variety, or pedigree. Genotyping techniquesinclude Isozyme Electrophoresis, RFLPs, RAPDs, AP-PCR, DAF, SCARs,AFLPs, SSRs which are also referred to as Microsatellites and SNPs.

The variety described herein has shown uniformity and stability for alltraits, such as described in Table 1. When preparing the detailedphenotypic information, plants of variety CL233163 were observed whilebeing grown using conventional agronomic practices.

Variety CL233163 can be advantageously used in accordance with thebreeding methods described herein and those known in the art to producehybrids and other progeny plants retaining desired trait combinations ofCL233163. Provided are methods for producing a canola plant by crossinga first parent canola plant with a second parent canola plant whereineither the first or second parent canola plant is canola varietyCL233163. Further, both first and second parent canola plants can comefrom the canola variety CL233163. Either the first or the second parentplant may be male sterile.

Still further, methods to produce a CL233163-derived canola plant areprovided by crossing canola variety CL233163 with a second canola plantand growing the progeny seed, and repeating the crossing and growingsteps with the canola CL233163-derived plant at least 1, 2 or 3 timesand less than 7, 6, 5, 4, 3 or 2 times. Any such methods using thecanola variety CL233163 may include one or more of open pollination,selfing, backcrosses, hybrid production, crosses to populations, and thelike. All plants produced using canola variety CL233163 as a parent,including plants derived from canola variety CL233163 are providedherein. Plants derived or produced from CL233163 may include componentsfor either male sterility or for restoration of fertility.Advantageously, the canola variety is used in crosses with other,different, canola plants to produce first generation (F₁) canola hybridseeds and plants with superior characteristics.

A single-gene or a single locus conversion of CL233163 is provided.Single-gene conversions and single locus conversions can occur when DNAsequences are introduced through traditional (non-transformation)breeding techniques, such as backcrossing. DNA sequences, whethernaturally occurring, modified or transgenes, may be introduced usingthese traditional breeding techniques. Desired traits transferredthrough this process include, but are not limited to, fertilityrestoration, fatty acid profile modification, oil content modification,protein quality or quantity modification, other nutritionalenhancements, industrial enhancements, disease resistance, insectresistance, herbicide resistance and yield enhancements. The trait ofinterest is transferred from the donor parent to the recurrent parent,in this case, the canola plant disclosed herein. Single-gene traits mayresult from the transfer of either a dominant allele or a recessiveallele. Selection of progeny containing the trait of interest is done bydirect selection for a trait associated with a dominant allele.Selection of progeny for a trait that is transferred via a recessiveallele will require growing and selfing the first backcross to determinewhich plants carry the recessive alleles. Recessive traits may requireadditional progeny testing in successive backcross generations todetermine the presence of the gene of interest.

It should be understood that the canola variety described herein can,through routine manipulation by cytoplasmic genes, nuclear genes, orother factors, be produced in a male-sterile or restorer form asdescribed in the references discussed earlier. Canola variety CL233163can be manipulated to be male sterile by any of a number of methodsknown in the art, including by the use of mechanical methods, chemicalmethods, SI, CMS (either ogura or another system) or NMS. The term“manipulated to be male sterile” refers to the use of any availabletechniques to produce a male sterile version of canola variety CL233163.The male sterility may be either partial or complete male sterility. F1hybrid seed and plants produced by the use of canola variety CL233163are provided. Canola variety CL233163 can also further comprise acomponent for fertility restoration of a male sterile plant, such as anRf restorer gene. In this case, canola variety CL233163 could then beused as the male plant in hybrid seed production.

CL233163 can be used in tissue culture. As used herein, the term plantincludes plant protoplasts, plant cell tissue cultures from which canolaplants can be regenerated, plant calli, plant clumps, and plant cellsthat are intact in plants or parts of plants, such as embryos, pollen,ovules, seeds, flowers, leaves, husks, stalks, roots, root tips, anthersand the like. Tissue culture and microspore cultures and theregeneration of canola plants therefrom are provided.

The utility of canola variety CL233163 also extends to crosses withother species than just Brassica napus. Commonly, suitable species willbe of the family Brassicae.

Molecular biological techniques allow the isolation and characterizationof genetic elements with specific functions, such as encoding specificprotein products.

The genome of plants can be engineered to contain and express foreigngenetic elements, or additional or modified versions of native orendogenous genetic elements in order to alter the traits of a plant in aspecific manner. Any DNA sequences, whether from a different species orfrom the same species, that are inserted into the genome usingtransformation are referred to herein collectively as “transgenes”. Geneediting can insert, delete or substitute native polynucleotide sequencesto produce increased or decreased expression or activity of apolypeptide of interest. Described herein are transformed and editedversions of the claimed canola variety CL233163.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. The mostprevalent types of plant transformation involve the construction of anexpression vector. Such a vector comprises a DNA sequence that containsa gene under the control of or operatively linked to a regulatoryelement, for example a promoter. The vector may contain one or moregenes and one or more regulatory elements.

In general, methods to transform, modify, edit or alter plant endogenousgenomic DNA include altering the plant native DNA sequence orintroducing a pre-existing transgenic sequence including regulatoryelements, coding and non-coding sequences. Genetic transformationmethods include introduction of foreign or heterologous sequences andgenome editing techniques which modify the native sequence.Transformation methods can be used, for example, to target nucleic acidsto pre-engineered target recognition sequences in the genome. Suchpre-engineered target sequences may be introduced by genome editing ormodification. As an example, a genetically modified plant variety isgenerated using “custom” or engineered endonucleases such asmeganucleases produced to modify plant genomes (see e.g., WO2009/114321; Gao et al. (2010) Plant Journal 1:176-187). Anothersite-directed engineering method is through the use of zinc fingerdomain recognition coupled with the restriction properties ofrestriction enzyme. See e.g., Urnov, et al., (2010) Nat Rev Genet.11(9):636-46; Shukla, et al., (2009) Nature 459 (7245):437-41. Atranscription activator-like (TAL) effector-DNA modifying enzyme (TALEor TALEN) is also used to engineer changes in plant genome. See e.g.,US20110145940, Cermak et al., (2011) Nucleic Acids Res. 39(12) and Bochet al., (2009), Science 326(5959): 1509-12. Site-specific modificationof plant genomes can also be performed using the bacterial type IICRISPR (clustered regularly interspaced short palindromic repeats)/Cas(CRISPR-associated) system. See e.g., Belhaj et al., (2013), PlantMethods 9: 39; The Cas9/guide RNA-based system allows targeted cleavageof genomic DNA guided by a customizable small noncoding RNA in plants(see e.g., WO 2015026883A1).

A genetic trait which has been engineered into a particular canola plantusing transformation and/or gene editing techniques, could be moved intoanother line using traditional breeding techniques that are well knownin the plant breeding arts. For example, a backcrossing approach couldbe used to move a transgene or modified gene from a transformed ormodified canola plant to an elite inbred line and the resulting progenywould comprise a transgene or modified gene. Also, if an inbred line wasused for the transformation or genetic modification then the transgenicor modified plants could be crossed to a different line in order toproduce a transgenic or modified hybrid canola plant. As used herein,“crossing” can refer to a simple X by Y cross, or the process ofbackcrossing, depending on the context. Various genetic elements can beintroduced into the plant genome using transformation or gene editing.These elements include but are not limited to genes; coding sequences;inducible, constitutive, and tissue specific promoters; enhancingsequences; and signal and targeting sequences.

Transgenic and modified plants described herein can produce a foreign ormodified protein in commercial quantities. Thus, techniques for theselection and propagation of transformed plants, which are wellunderstood in the art, may yield a plurality of transgenic or modifiedplants which are harvested in a conventional manner, and a foreign ormodified protein then can be extracted from a tissue of interest or fromtotal biomass.

A genetic map can be generated, for example via conventional RFLP, PCRanalysis, SSR and SNPs, which identifies the approximate chromosomallocation of the integrated DNA molecule coding for the foreign protein.Genetic or physical map information concerning chromosomal location isuseful for proprietary protection of a subject transgenic or modifiedplant. If unauthorized propagation is undertaken and crosses made withother germplasm, the map of the integration or modified region can becompared to similar maps for suspect plants, to determine if the latterhave a common parentage with the subject plant. Map comparisons wouldinvolve hybridizations, RFLP, PCR, SSR, SNP, and sequencing, all ofwhich are conventional techniques.
